in the accompanying drawings,v.1herein:- Referring now. to the drawings, and first Figure 1 is a perspective view of an impleto the form disclosed in Figures 1 to f? inclument constructed according to the present sive, 10 andll designate a pair ofsupportvention, the dotted lines showing the hand ing arms which are preferably of duralumi-p grasping the instrument for spreading the num or other suitable metal not subject to arms and Wipers thereof. V rust, and which also preferably have an in Figure 1-21 's a fragmentary. sectional herent spring characteristic for maintaining view of the upper end of the implement as the arms .10 and 11 substantially in parallel applied. to apaneofglass and having hoods relation and admitting. of the springing of we the arms apart when desired. The arms 10 and 11 at one end, which may be termed the lower end of the implement, are offset inwardl to provide a pair of shanks which are a apted to abut in face relation and are secured rigidly together by rivets 13 or the like as shown in Figure 1. The onset portions of the arms 10 and 11 may be in any suitable shape for the purpose of design, and also for the purpose of spacing the arms 10 and 11 apart to the desired extent, and further for the purpose of resiliently connecting the arms 10 and 11 together so that the arms may flex under pressure for s1 reading the arms as shown by the arrows in Figure 1, and so that the arms 10 and 11 by their inherent resiliency will spring backwardly into normal position as shown by the inside arrows.

The arms 10 and 11 are preferably disposed in parallel relation throughout their upper or len th and are consequently spaced apart at them outer end. Each arm is provided with a wiper element, and each element may comprise a perforated casing 14 of sheet metal or the like and which may be of box like structure, the casing 14 being open at one side and adapted to receive therein a filler block 15 of cork or other non-absorbent material, light in weight.

The filler block 15 is provided with a pad 16 upon its outer face which may be formed of any suitable water absorbing material and which is held in place by a cover strip 17 of porous flexible material which is wrapped in one direction around the block 15 and has its free ends 18 locked against the inner side of the block 15, as shown in Figure 4. A holding strip or late 19, of wood, veneer or the like, is fitte over the ends 18 of the cover strip 17 and, when the device is assembled is adapted to hold the free ends 18 rigidly upon the block 15. An outer contact strip 20 is fitted over the outer side of the retaining strip 17 and preferably extends at right anfiles thereto, as shown in Figures 4 and 5, and

as its free ends upturned against the side of the block 15 and held in place by pin 21 or the like. When the filler block 15, with its parts, are assembled as shown in Figure 5, it is inserted in the casing 14 so that the parts are assembled as shown in Figure 7. It will be noted that the pins 21 engage through openings in the opposite sides of the casing 14 and through openings 22 which are formed in the free end of the outer covering strip 20, so that the covering strip 20 is held se curely on the wiping element.

The casing 14 is provided in one end with a slot 23 which is located near the closed side of the casing 14 and is of sufiicient size and so shaped as to slidably receive the free end of one of the arms, such as the arm 10 therein. The arm 10 is adapted to be slid inwardly through the slot 23 to the desired extent, such as shown in Figure 6, when the arm 10 is secured to the casing and also the filler block by means of screws 24 or the like.

The screws 24 are passed inwardly through openings 25 which are formed in the closed side of the casing 14, and these openings 25 may be in any desired number and arrangement so as to receive the screws 24 for variously adjusting the arm in the casing. From Figure 6 it will be noted that the arm 10 is of sufficient thickness to take up the space between the closed side of the casing 14 and the cover strip or plate 19, and that the screws 24 engage through the casing, the arn'i 10, the plate 19 and the overturned ends 18 of the retaining strip 17, and finally are threaded into the block 15. Each arm, such as the arm 10, is provided with spaced openings 25 for the reception of the screw 24, and it will be apparent that when the arm 10 is slid more or less into the casing to register with the desired opening 25, the wiper ele ment may be adjustably secured upon the upper end of the arm 10.

These wiping elements are adapted to carry a certain amount of moisture or water and may be dipped into a bucket or the like prior to the application of the implement to the window.

In applying the implement to a window, and such as to the lower sash thereof as shown in Figures 2 and 3, the lower sash 26 is raised in the window casing 27 so as to leave a space between the lower edge of the sash 26 and the window sill 28. The arms 10 and 11 of the implement are now spread apart so as to spread the wiping members sufficiently to receivethe lower edge of the sash 26 there between, and the implement is thus positioned upwardly with a wiping member against each side of the sash.

As soon as the arms 10 and 11 are released, the resiliency of the arms causes the wiping members to immediately close or move toward each other and bind against the opposite sides of the pane of the window sash 26. By grasping either of the arms 10 and 11, or both of them, or the lower end of the implement, the implement may be raised and lowered or moved back and forth in any desired direction so as to rub the wiping elements over the opposite sides of the pane of glass. The advantage of this structure is that it is unnecessary to lean out of the win dow or to reach against the outside of the sash because the operator may grasp the inner arm, such as the arm 10, and move the entire implement as a unit in the desired direction.

Referring now to the modification of the invention which is disclosed in Figures 8, 9 and 10, the implement comprises a pair of arms 29 and 30 which may be relatively rigid and connected together at their lower ends by a bowed U shaped spring 31. The spring 31 is disposed between the lower ends of the arms 29 and 30 andthe opposite sides of the spring are riveted or otherwise suitably se-- sheet metal imperforate casing 33 having suitable depth to receive in the open side thereof a filler block 34 of cork or the like. The block 34 is provided with the crossed flexible strips 35 and 36, the strip 35 engaging an absorbing pad 37 of felt or the like which is disposed against the outer side of the block 34 The free ends of the strip 35 are lapped against the inner side of the block 34, as shown in Figure 10, and the free ends of the strip 36 are merely turned upwardly against the opposite edge portions of the block 34 and are adapted to be secured in positlon 1n the same manner as is shown in connection with the strip 20 in Figures 5 and 7.

The overturned ends of the strip 35 are adapted to receive there-across the free end portion of the adjacent arm, such as the arm 29, and are held in place with screws 38 wh1ch engage thru the casing 33 and thru the overturned ends of the strip 35, and are threaded into the block 34. If desired, spacers 39 may be placed against the inner side of the block 34 between the'overturned ends of the strip 35 and the inner side of the casing 33 so as to'provide ample space for the arm 29.

, '7 This form of the invention is applied and used in the manner above described, the structure however being slightly different than the preferred form and adapting the device to more economical manufacture under some conditions.

Referring nowto the modifications shown in Figures 11 to- 14, the implement is provided with a pair of spring arms 40 and 41 which are offset inwardly toward each other as shown at the lower end of Figure 11 and are secured together attheir lowerends by rivets 42. In order to vary the tension on the outer ends of the arms 40 and'41, an adjusting bolt 43 is secured through the lower end portions of the arms 40 and 41' above the offset portions of the arms and is provided with a thumb nut 34 adapted to be turned up against'the outer side of one of the arms, such as the arm 41, for drawing the bolt 43 through the arms and thus urging the arms toward each other at their free ends to a greater extent. a

In this form of. the invention one of'the depression or socket 45 for receiving the free end of the arm- 44 when the latter is extended, as" shown in full lines in Figure 11. The

dotted lines in Figures 11 and 12 show. the

arm 44 Whennot in use, and at which timethe arm hangs downwardly against the inner sideoffthe arm 41.

The structure of the wiping element shown in the form of the invention in Figures 111 to 1'4is slightly modified and a chamois 46 or other suitable wiping cloth is stretched across the outer side of the block 47 by a pad 48"of fibrous material, the pad being en largedto extend beyond the sides and ends of the block 47 andthushold the chamois 46 beyond the casing 49 tocover a relatively large surface area.

The spacing arm or rod 44 is employed when it is desired'to' hold the wiping elements apart, as shown in Figures 11 and 12,

and the rod or bolt 43 is employed for holdabove specifically described embodiments of this invention, without departing from the spirit thereof, the changes and modifications being restricted only by the scope of the following claims.
